| Part-of-speech (POS) tagging is one of the most basic operations of computational linguistic. Since it helps to disambiguate syntactic categories (and possibly senses), POS are regularly used in various natural language processing (NLP) tasks such as parsing, sentence classifying, word sense disambiguation etc. The big challenge for POS tagging is the training data. Supervised algorithms for POS tagger perform well on resource-rich languages where manually annotated data is available. Unsupervised POS tagging, on the other hand, does not need any manually annotated data and particularly suitable for resource-poor languages.
The goals of the project include to study the current approaches for POS tagging for both resource-rich and resource-poor languages and develop taggers for resource-poor languages based on POS knowledge from resource-rich languages. |
